Summary

The Complete Guide to Writing Maintainable, Manageable, Pleasing, and Powerful Object-Oriented Applications 

 

Object-oriented programming languages have a point of view about how best to model the world. They exist to help you create beautiful, straightforward applications that are easy to change and simple to extend. Unfortunately, the world is awash with object-oriented (OO) applications that are difficult to understand and expensive to change. Even though they’re written in OO languages, these applications fail to achieve the promise of OO because their code doesn’t reflect the right mindset. The purpose of Practical Object-Oriented Design, Second Edition, is to solve that problem by immersing you in an OO mindset. It teaches powerful, real-world, object-oriented design techniques using simple and practical examples. It will change the way you think about code.

 

Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a proven set of OO practices for crafting manageable, extensible, and pleasing code. She demonstrates how to build new applications that can “survive success” and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples in the easy-to-understand Ruby programming language, all downloadable from the companion Web site, poodr.com. Fully updated for Ruby 2.5, this guide shows how to:

  • Decide what belongs in a single class
  • Avoid entangling objects that should be kept separate
  • Define flexible interfaces among objects
  • Reduce programming overhead costs with duck typing
  • Successfully apply inheritance
  • Build objects via composition
  • Design cost-effective tests
  • Solve common problems associated with poorly designed object-oriented code

Whatever your previous object-oriented experience, this concise guide will help you achieve the superior outcomes you’re looking for.
